GPS Camera Positioning via Satellite and Network Signal Fusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing GPS-enabled cameras and mobile stations face delays in determining location fixes and lack configurability, as they do not integrate satellite and wireless network data effectively, leading to inefficiencies in capturing images with accurate location tags.
Innovation Solution
A method and device that capture images by determining a position based on both satellite and wireless network signals, allowing for flexible and robust position location by integrating GPS and wireless network data, and tagging images with the determined position, which can be done for single or batch images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS-enabled cameras use Standalone GPS to determine location fix after each photograph, then location data can be obtained, but substantial delays occur in determining the location fix
Solution Approach 1:
The patent combines GPS satellite signals with wireless network signals to determine location. The system integrates multiple positioning methods (GPS and network-based positioning) to work together, allowing the device to use wireless network data to assist GPS acquisition and reduce the time to obtain a location fix while maintaining accuracy.
Solution Approach 2:
The system performs preliminary actions by continuously monitoring wireless network signals and maintaining a cache of location data before GPS signals are available. When GPS acquisition is needed, the system already has preliminary location information from network signals, reducing the overall time to determine an accurate location fix.
2Adaptability or versatility
If GPS-enabled cameras operate independently with separate camera and GPS functions, then each function can operate autonomously, but the system lacks user configurability and integration with wireless network data
Solution Approach 1:
The patent creates a universal positioning system that can operate in multiple modes: GPS-only mode, network-only mode, and combined GPS-network mode. The system provides multi-functionality by accepting various signal sources and processing methods, allowing it to adapt to different operational requirements and environments while maintaining a unified interface for the user.
Solution Approach 2:
The system dynamically adjusts its operation mode based on available signals and user preferences. It can switch between different positioning methods (GPS, network-based, or combined) and allows users to configure real-time preferences for how location data is obtained and used, making the system flexible and adaptable rather than static and rigid.
3Productivity
If GPS-enabled cameras determine location after image capture, then the camera can capture images immediately, but batch processing is required to combine pictures with location data
Solution Approach 1:
The system determines the location fix before capturing the image by using wireless network signals to obtain preliminary location data in advance. This preliminary action ensures that when the image is captured, the location data is already available and associated with the image metadata, eliminating the need for subsequent batch processing to combine the two data sets.
